CNN News:英美签署协议 联手保护泰坦尼克号残骸

Which of these ships sank in April of 1912? RMS Titanic, SS Eastland, RMS Lusitania, or Endurance. All of these ships sank in 1915 except the Titanic which was lost on April 15th, 1912.
A British government minister says the wreck of the Titanic is the most documented maritime tragedy in history. On the night of April 14th when the so called unsinkable ship hit the iceberg that caused it to sink, Titanic was on its maiden voyage from the United Kingdom to the United States. Now those two countries have ratified a treaty that's intended to protect the ship's remains. The law gives Britain and America the power to grant or deny licenses for explorers to send submersibles inside the wreckage and to remove any artifacts they find outside of it. British officials say this will ensure the Titanic is treated with the sensitivity and the respect it deserves but that wreck as it sits now won't stay that way forever. Images from a recent dive there show the ship is sinking deeper into the ocean floor and being corroded by bacteria there.
